*This sandwich plate was designed to only be used with an M22 Sandwich Plate Adapter.


The Mishimoto Thermostatic Oil Sandwich Plate is a lightweight, high-flow sandwich plate built from 6061 aluminum. It’s used to add an external cooler to your vehicles oil system. The built-in thermostat prevents oil flow to the cooler until the engine oil reaches activating temperature, allowing for both a faster warmup at startup and extra oil system protection in cold climates.


The included 185°F (85°C) thermostat can be replaced with a 160°F (71°C) or 200°F (93°C) unit, adding unparalleled control over your desired engine oil operating temperature. This Oil Sandwich Plate is designed specifically for M22 Stainless Steel Center Bolts and includes a 1/8" NPT plugged port on the side for an optional sensor or gauge as well as our Mishimoto Lifetime Warranty.
